nRF connect SDK calendar

[ianbkk]

Hi, I'am working on a project were I need to use RTC as a calendar on nRF connect SDK but I have not found anything about it, what I found was the calendar for the nRF5 calendar, but it doesn't work on nRF connect SDK, I was wondering if anyone knows how I can adapt the code for nRF connect SDK.

Zephyr has a built-in calendar: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/kernel/timeutil.html.

do you know if there is any exemple code for this calendar?

I can't find any sample, but you can find the API's you need from your C library implementation. 
See f.ex modules\lib\picolibc\newlib\libc\time
